Objective: This study aimed to assess the reliability and agreement of automated head measurements (OFC, cephalic index, and volume) using 3D photogrammetry in young children.
Materials and Methods: The study evaluated the agreement between manual and automated occipitofrontal circumference (OFC) measurements (n=264) obtained from 3D images of 188 patients diagnosed with sagittal synostosis using a novel automated method proposed in this study.
Results: The results of the study showed that the automated OFC measurements had excellent agreement with manual measurements, with a very strong regression score (R2 =0.969) and a small mean difference of -0.1 cm (-0.2%). The limits of agreement ranged from -0.93 to 0.74 cm, falling within the reported limits of agreement for manual OFC measurements. High inter-rater and intra-rater reliability of OFC, cephalic index, and volume measurements were also demonstrated.
Conclusions: The proposed method for automated OFC measurements was found to be a reliable alternative to manual measurements, which may be particularly beneficial in young children who undergo 3D imaging in craniofacial centers as part of their treatment protocol and in research settings that require a reproducible and transparent pipeline for anthropometric measurements. The method has been incorporated into CraniumPy, an open-source tool for 3D image visualization, registration, and optimization, which is publicly available on Github.
